在系统研究冬小麦干旱ＮＯＡＡ／ＡＶＨＲＲ遥感监测理论、模型、资料处理、指标及应用技术的基础上，建立了河南省冬小麦干旱ＮＯＡＡ／ＡＶＨＲＲ遥感监测模型，针对这一领域中存在的问题，在ＧＩＳ技术的支持下，进一步探讨了不同土壤质地和风速对遥感干旱监测的影响、用遥感表层土壤水分反演深层土壤水分的方法与模型、用单时相遥感资料反演土壤水分的方法等。在上述工作的基础上，建立了河南省冬小麦干旱遥感监测应用服务系统。 Based on systematically studying the theory, model, data processing, index and application technology of NOAA / AVHRR remote sensing monitoring of winter wheat drought, the remote sensing monitoring model of NOAA / AVHRR in winter wheat in Henan Province was established. In view of the existing problems in this field, , This paper further explores the effects of different soil texture and wind speed on the monitoring of remote sensing droughts, the methods and models for the retrieval of deep soil moisture by remote sensing surface soil moisture, and the retrieval of soil moisture using single-phase remote sensing data. Based on the above work, a drought remote sensing monitoring application service system for winter wheat in Henan Province was established.
